A beautiful Egyptian princess, Femi was involved with a cult known as The Undying. This group repudiated the Gods, believing that mankind was itself the highest form of life – they frequently shouted “God Is Dead!” as a way of displaying their blasphemous beliefs. In retribution, the priests of Egypt captured Femi and mummified her, using special magicks to keep her alive, in an eternal sleep. In the modern day, she managed to make a psychic connection with a man who had bought her corpse, intending to display it in his house. The man used a powerful gem to revive Femi, who was reunited with the remains of The Undying. Femi was now able to control the undead but her power came with a price — she now had to feed on human flesh to remain young.The exact process that Femi uses to create her armies of mummified warriors is mystical in nature and bestows upon her followers great strength and durability.

Though she was destroyed in her first battle with Assistance Unlimited, she was later revived by Walther Lunt. Since then, Femi has been revived on several occasions and even served as a member of Murder Unlimited.
